            Male (PBI_OON_0037747). Total length 1.24. CEPHALOTHORAX: Carapace pale orange, without any pattern, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, with rounded posterolateral corners, posterolateral edge without pits, posterior margin not bulging below posterior rim, anterolateral corners without extension or projections, posterolateral surface without spikes, surface of elevated portion of pars cephalica finely reticulate, sides finely reticulate, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin undulate, rebordered, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae needle-like, present, scattered; non-marginal pars thoracica setae needle-like; marginal setae needle-like. Clypeus margin slightly rebordered, curved downwards in front view, vertical in lateral view, high, ALE separated from edge of carapace by their radius or more, median projection absent; setae present, needle-like. Chilum absent. Eyes six, well developed, all subequal, ALE circular, PME squared, PLE circular; posterior eye row procurved from both above and front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by PME radius to PME diameter. Sternum as long as wide, pale orange, uniform, not fused to carapace, median concavity absent, with radial furrows between coxae I-II, II-III, III-IV, furrow smooth, radial furrow opposite coxae III absent, surface smooth, without pits, microsculpture absent, sickle-shaped structures absent, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV, anterior corner unmodified, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins unmodified, without posterior hump; setae sparse, needle-like, evenly scattered, originating from surface, without hair tufts. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae slightly divergent, anterior face unmodified; fangs without tooth-like projections, directed medially, shape normal, without prominent basal process, tip unmodified; setae needle-like, evenly scattered; paturon inner margin with pairs of enlarged setae, distal region abruptly narrowed, posterior surface unmodified, inner margin unmodified, laminate groove absent. Labium rectangular, anterior margin indented at middle, same as sternum in sclerotization, fusion to sternum unsure (broken off); with 3-5 setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, same as sternum in sclerotization, endites anteromedian tip with simple indistinct protrusion, posteromedian part with broad triangular projection. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions yellowish ground color, purple-brown dots and insdistinct wide net-like pattern, cardiac mark pale. Book lung covers large, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles not connected by groove. Pedicel tube short, ribbed, scuto-pedicel region unmodified, scutum extending far dorsal of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent, cuticular outgrowths near pedicel absent. Dorsal scutum weakly sclerotized, pale orange, without color pattern, covering about 1/2 of abdomen, between 1/4 and 1/2 abdomen width, fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles, narrow rectangular (hard to recognize due to weak sclerotization). Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum weakly sclerotized, pale orange, short, almost rectangular, covering about 1/3 of the abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring, divided into 2 platelets. Dorsum setae present, needle-like. Epigastric area setae uniform, needle-like. Postepigastric area setae present, needle-like. Spinneret scutum without fringe of setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present, small plate with 2 setae. Spinnerets: ALS: not examined; PMS: not examined; PLS: not examined. LEGS: pale orange, without color pattern; femur IV not thickened, same size as femora I-III, tibia I unmodified, tibia IV specialized hairs on ventral apex absent, tibia IV ventral scopula absent, metatarsi I and II meso-apical comb absent , metatarsi III and IV weak ventral scopula absent, tibiae emerit's glands not examined, metatarsi patch of short setae distoventrally at metatarsi I and II not detectable (missing leg part), tarsi pairs of special setae with distinct flattened clawlike apexes present on tarsi III, IV. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I p0-1-1; II p0-0-1; tibiae: I v4-2-2; II v4-2-1p; IV v0-1-2; r1-1-0; metatarsi: II v2-2-2; (leg I: other legparts missing, leg IV: uncertain due to broken off spines and missing legparts. ). Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Epigastric region with sperm pore large, oval, situated at level of anterior spiracles, unmodified; furrow without omega-shaped insertions, without setae. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments pale orange; embolus dark, prolateral excavation absent, basaly broad, distally narrow tube-shaped, moderately curved prolaterad, longitudinally moderately folded with ventral cavity, retrolaterally with distinct rim (tip broken off in SEM scanned specimen); trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella basally; patella shorter than femur, not enlarged, without prolateral row of ridges, setae unmodified; tibia basally moderately inflated, trichobothria with 3 trichobothria; cymbium pale orange, narrow in dorsal view, not fused with bulb, not extending beyond distal tip of bulb, plumose setae absent, without stout setae, without distal patch of setae, cymbial cone not detected, tarsal organ with 2 sensilla (appearing as 3?); bulb yellow, 1 to 1.5 times as long as cymbium, stout, tapering apically, distal part conductor originates at middle of embolus, broad lamelliform elongated and bent, simply broad truncated, as long as embolus.
